simplify ln(4xe^{-4x})

Solution

simplify

ln (4 x e^{- 4 x})

Solution

2 ln (2) + ln (x) - 4 x

Solution steps

ln (4 x e^{- 4 x})

Apply log rule:

lo g_{c} (ab) = lo g_{c} (a) + lo g_{c} (b)

ln (4 x e^{- 4 x}) = ln (4) + ln (x) + ln (e^{- 4 x})

= ln (4) + ln (x) + ln (e^{- 4 x})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (e^{- 4 x}) = - 4 x ln (e)

= ln (4) + ln (x) - 4 x ln (e)

4 x ln (e) = 4 x

= ln (4) + ln (x) - 4 x

ln (4) = 2 ln (2)

= 2 ln (2) + ln (x) - 4 x
